COMBINATION ADJUSTABLE PLOW AND CULTI VA I'OF Z.

SPECIFICATION forming part of Letters Patent No. 732,626, dated June 30, 1903.

Application filed June 16,1902. Serial No. 111,885- (No model- To all whom it may concern:

description of the same.

Myinvention relates to improvements in adjustable plows and cultivators; and it consists in the construction and combination of de vices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of an adjustable plow and cultivator embodying my improvements. Fig. 2 is a side elevation of the same. Figs. 3 and 4 are detail views of the .plows, their standards, and the arms by which they may be turned.

In the embodiment of my invention I provide a frame 1, which may be of any suitable construction. The same is here shown as comprising a pair of longitudinally-disposed side bars 2 3, appropriately spaced apart, and the former shorter than the latter and disposed abreast of the front portion thereof, a pair of substantially U shaped yokes 4, which connect the front portion of said bars 2 3 together and are bolted on their upper and lower sides, and cross-bar 5, which connects said bars 2 3 together at a suitable distance from their front ends, and beam 6, which is disposed obliquely with reference to said bars 2 3 and is secured thereto, and a rearwardlyextending bar 7, which has its front end securely attached to the beam 6, near the center of the latter. The length of the beam 6 is such that its ends projectbeyond the outer sides of the bars 2 3. Said bars 2 3 are fur ther connected together at suitable points above the beam 6 by arch-bars 89, which are disposed the former in advance of the latter, and said arch-bars are curved, as shown in Fig. 1, and'in practice may be provided with rack-teeth for the purpose hereinafter stated.

On the under sides of the bars 2 3, near the front end thereof, are bearings 10, in which is journaled an axle-shaft 11, which is provided at its right-hand end with an arm 12, that extends at right angles thereto, or substantially so, which arm has a spindle 13 at its outer end, said spindle carrying. a front supporting-wheel14, as shown. Thesaid axleshaft is further provided with an upwardlyextending rock-arm 15.

The bars 3 7 are provided near their rear ends on their lower sides with bearings 16 for an axle-shaft 17, which has an upwardly-extending rock-arm18 and is provided at its .It will be understood that by moving this lever laterally the link 26, rock-arms 15 18, and rod 22 will cause the axle-shafts to partly turnin their hearings to impart angular ver-- tical movement to their arms, which carry the wheels 14 21, and hence the frame will be raised or lowered, according to the direction in which said lever 23 is moved. Said lever bears on the arch-bar 8 and in practice is provided with a suitable locking-dog to coact with said arch-bar to lock said lever at any desired adjustment.

To facilitate the vertical adjustment of the frame 1 and the plows or cultivators which it carries, I further provide pedal-lever 27, on which the driver, seated on seat 28, may place one of his feet, the said pedal-lever being adapted'to be operated by the driver simultaneously with thelever 23. Said pedal-le= ver is directly attached to the axle-shaft 17,

which carries the rear supporting-wheel 21.

A third wheel 29, which is a trail-wheel, is carried by a fork 30, having a shank 31, which is mounted in suitable bearings 32 and is movable vertically in the said bearings to admit of the vertical adjustment of the frame 1 in the manner and by the means'hereinbefore described independently of said trail-wheel.

The obliquely-disposed beam6 is provided with bearings for the vertical standards 33 'of a suitable number of plows or cultivat'orpoints 34. The said standards are also proto overcome side draft and to enable the machine to be employed for sidehill plowing as well as for plowing level land. It will be furthermore understood that by appropriately adjusting the plows or cultivators the machine may be caused to move laterally in eitherdirection while being drawn forwardly, so as to cause it to operate close to trees and the like and also enable it to be readily guided to avoid obstructions. Each of the standards 33 is provided at its upper end with a rockarm 36, forming, in effect, a tiller. The said rock-arms or tillers are connected together by connecting-rods 37, which cause them to move in unison, and one of the said standards 33 is further provided with a rock-arm 38.

A draft-head 39, which may be of any suitable construction, is pivotally mounted at the front end of the frame, either as here shown by the pivot 2a of the lever or by other suitable means, and said draft-head has a centrally disposed rearwardly extending arm 40. The latter has near its rear end a pivot 41, which operates in a slot 42 in the front end of a lever 43, which lever extends rearwardly to within convenient reach of the driver on the seat 28 and is fulcrumed, as at 44, on the cross-bar 5 and is connected by the rod 45 to the arm 38, which forms the adjusting arm or element of the plurality'of simultaneously adjustable plows or cultivators. This rod 45 is adjustably connected, as at 46, to the lever 23. It will be understood that by means of said lever and its connections the plows or cultivors may be simultaneously adjusted as may be required and that the draft head or element 39 willalso be simultaneously adjusted.

The lever 43 operates on the arch-bar 9 and in practice is provided with coacting means, as a locking-dog or the like, to secure said lever to the arch-bar when the lever is disposed in any desired position.

I do not desire to limit myself to the precise construction and combination of devices here inafter shown and described, as it is evident that modifications may be made therein without departing from the spirit of my invention and within the scope of the appended claims.

Having thus described my invention, I claim 1. In a plow of the class described, the combination of a frame, axle-shafts carried thereby havingangularelements and rocking arms, supporting-wheels carried by said angular elements, a connection between the rocking arms, and a transversely-swinging lever having an angular arm linked to the said connection, substantially as described.

2.
